Is Lemon Curd Keto?
Regular lemon curd is not keto (so much sugar), but this easy low carb lemon curd is keto friendly! Each tablespoon serving has just 1/2 gram of net carbs.
For the smoothest lemon curd, the sweetener makes a huge difference! That’s why this recipe uses Besti Monk Fruit Allulose Blend. It dissolves effortlessly into the lemon curd, so it’s never gritty — with no added net carbs!
Ingredients You’ll Need
This section explains how to choose the best ingredients for keto-friendly lemon curd, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
- Butter – Use unsalted.
- Lemons – You’ll need about 3-4 whole lemons, as we’re using both fresh lemon juice and zest.
- Egg Yolks – Using the yolks only gives this lemon curd a luxurious texture. Make sure they are at room temperature before you begin. Save the whites and make a keto lemon meringue pie or keto bread!
- Besti Monk Fruit Allulose Blend – The best way to have all the sweetness of sugar without the sugar and carbs. Unlike other sweeteners (including erythritol and other brands of monk fruit sweetener), Besti dissolves completely and won’t crystallize, which is why it’s the only one I recommend for this sugar free lemon curd recipe. It’s also fine to use Besti Powdered — both versions dissolve easily.
- Sea Salt – To balance the sweetness.

0I made this and did not like it at all, it tastes like it had too much salt. what did I do wrong? I followed the recipe to a tee.
Wholesome Yum D
0Hi Nancy, Sorry this recipe didn’t turn out as expected. The recipe only called for 1/4 tsp of salt so over 20 servings it should be that noticeable.
Angelia
0Can I use my juicer for the lemons? Thought might be easier and yummier? Thoughts?
Wholesome Yum D
0Hi Angelia, I have never tried but let me know the results if you do.
Sally Rigsby
0All I have on hand is salted butter. Can I use that and not add the addition of sea salt? I also have allulose. Would that crystallize (monk fruit raises my bs)?
Wholesome Yum D
0Hi Sally, Yes, salted butter would be ok. If you are using another sweetener you’ll want to use my Keto Sweetener Guide to make sure you use the correct amount.
Judith Bell
0Easy and delicious! A great way to use the surplus meyer lemons we have this time of year.
Amy Hunter
0This called for 1/2 cup of butter. Is that correct? I feel like that was way too much. I’ve seen other recipes that at the most called for 5 tablespoons.
Wholesome Yum D
0Hi Amy, This is the correct amount of butter.
Nancy Onque
0I made this recipe and followed it exactly, but it has a metallic taste. Any suggestions?
Wholesome Yum D
0Hi Nancy, I’m not sure why that would have happened. Did you use Besti Monk Fruit Allulose Blend?
Jezzie
0Hi! I think I know what happened because it’s happened to me before! You must use a stainless steel saucepan or double broiler (or glass). Do NOT use aluminum or copper. 🙂 Look it up for more details.
Sandy
0We cook with lemon curd all the time, and now I have a delicious KETO option. Thank you!
Shelby
0I have officially now put this lemon curd on everything! It’s so tasty and it’s so far worked on cookies, overnight oats, and my morning oatmeal hehe.
Vit
0It was a perfect match to the vanilla ice cream 🙂 I’m a big fan of ice cream, so I made this sugar free lemon curd since there is already so much sugar in ice cream.
Margaret G
0How do you keep monk fruit from crystallizing in your recipe?
Wholesome Yum D
0Hi Margaret, Did you use Besti Monkfruit Allulose Blend?
Audra
0Does this curd recipe crystalize when chilled? I have made others with different sugar substitutes and get varying levels of crystallization that needs warming to smooth out the crunch. I love my lemon curd.
Thank you in advance.
Maya | Wholesome Yum
0Hi Audra, Using Besti it will not crystallize at all. 🙂
Maggie
0So so good! I followed your recipe and it turned it perfectly!
Hayley Dhanecha
0Keto lemon curd turned out so good. So refreshing, delicious, and guilt-free! Thanks for the recipe.
Sharon
0This lemon crud is so easy to make and has just the right balance of sweet and citrus. Great for topping yogurt with.
Katie Crenshaw
0Oh wow! This lemon curd is bursting with flavor! It is such a lovely treat without the sugary guilt!
Erin
0This curd looks amazing! I’m amazing you could make it keto. Can’t wait to try!
Lauren Michael Harris
0So glad that I found this recipe! I love lemon curd but have been cutting back on sugar. This was perfect!
Mikayla
0Tried this and a keto pancake recipe and wow it was really great together. Thank you, love a fruit topping that I do not feel guilty eating.
Heidy
0Sugar-free lemon curd is now a NEW FAVORITE OF MINE! How can you go wrong being Suger-free and Keto? It was so refreshing and delicious tasting. This is a keeper recipe that I will be making again!
Nancy
0I have a big bag of monkfruit sweetener and now I know exactly what to do with it. The lemon curd looks mouthwatering.
Patricia Farrell
0Excellent instructions my grandchildren love it and it turned out really good and tastes great. Thank you Patricia
Sue
0Is there a recipe for a CRISP Cookie? All that I find are actually soft style. I love lemon and would like a recipe for a low carb crisp lemon cookie. I thought of mixing a grated cheese with a sweetener and lemon zest and lemon flavor – kind of like they make cheese crackers, but I’m not confident formulating a recipe. Any ideas? It would certainly help keep me on low carb.
Wholesome Yum D
0Hi Sue, I currently don’t have any recipes like that but I will add it to my list to experiment.
Agnes
0I’ve never made homemade lemon curd before- didn’t realize it was this simple! I’ll have to try this the next time I make baked blueberry oatmeal bars, I love putting lemon curd on top of it!
Jessica
0This was absolutely FABULOUS! By far my new favorite treat to have in the summer. Thank you!
Sheila G
0The BEST!! I can eat this with a spoon but I also love it on top of muffins!
Pamela Ebertz
0Could I can this recipe? Instead of keeping it in the refrigerator?
Maya | Wholesome Yum
0Hi Pamela, Yes, I think you can, but I have not tried it.
Marcia
0Can I use powdered stevia?
Maya | Wholesome Yum
0Hi Marcia, I don’t recommend stevia as it has an aftertaste. Also, pure stevia doesn’t have the bulk/volume that Besti does, and if you use a stevia blend, these typically don’t dissolve properly.
Tami Proctor
0Lemon Curd is one of my favorites! Thank you for the recipe it’s delicious!
Lana McQuown
0I made this curd to go with a lemon meringue chaffle. It was delicious with the perfect balance of sweet and tartness. I can’t believe how easy it was to make. I can see it being used it all kind of other recipies. Thanks for creating such wonderful recipes.
Loreto and Nicoletta
0Hi Maya, this is a great take on lemon curd with a keto twist!👍👌❤️ Great tip on sweetness to use and this curd is so versatile, however, one of my favorites is lemon meringue! Thanjs for sharing!❤️❤️🥰👍
Barbara
0If I use less monk fruit, will that affect consistency?
Maya | Wholesome Yum
0Hi Barbara, It might, I haven’t tried that!
Nancy
0Hi Maya! This looks delicious! I’m ready to try this after having gathered about a dozen fresh lemons from my friends’ tree in California! Quick question: how would straight liquid monk fruit work? I like this because it’s cleaner and there’s no issue with grittiness or fiber at all. Have you tried this option at all?
Maya | Wholesome Yum
0Hi Nancy, We don’t recommend a liquid sweetener in this recipe, as it would be too runny. There is no fiber in Besti.
Dee
0About how long will the Lemon Curd keep in the fridge?
Maya | Wholesome Yum
0Hi Dee, It will keep in the fridge for 1-2 weeks.
Terra
0Hi Maya! Appreciate the email today about Fruity keto recipes for spring and plan on making both the sorbet and lemon curd. May be a dumb question, but wondering if straining the seeds out (for diverticulosis) would change the macros from keto to low carb since I’d be removing fiber? Also, while I can figure out how to swap other berries, what would you suggest to make lemon or lime sorbet or sherbet. Thanks for all you do!!
Maya | Wholesome Yum
0Hi Terra, Straining out seeds would remove fiber, but it would also remove the component of total carbs contributed by the fiber, so the net carbs should stay about the same. We haven’t experimented with a lemon or lime sorbet yet.
Laurie S Burke-Deutsch
0Can this recipe be made thick enough to use as a pie filling? Thank you. This sight is fantastic!!!
Maya | Wholesome Yum
0Hi Laurie, It’s a little thin for a pie filling. You can see a modified version used for this keto lemon meringue pie recipe.
Nellie Tracy
0This is a great lemon curd recipe! So delicious!
Britni
0I still can’t believe this is sugar free, it was soooo good! I’ll never use a regular lemon curd recipe again!
